As part of the initiative, a network of air quality sensors will be deployed across the capital, measuring pollution levels in tens of thousands of locations. Findings from the project will be shared with other cities across the UK and globally, including the C40 Cities Climate Leadership Group.

From July onwards, more than a hundred low-cost air quality sensors are being attached to lampposts and buildings in the worst-affected and most sensitive locations in the capital. These fixed sensors will be deployed alongside mobile sensors carried by Google Street View cars taking readings every 30 metres.

It is hoped that the resulting 'hyperlocal' network of sensors will create the world’s most sophisticated air monitoring system. Improving the monitoring of London air quality in this way should help identify those initiatives that make the biggest contributions to cutting air pollution.

Cambridge's Department of Chemistry is a pioneer in the use of low-cost sensors for the measurement of air quality and our researchers have used them in projects at Heathrow airport, in Beijing, and most recently Dhakar. Their role in this project is providing expertise in low-cost air quality sensors, and the analysis and interpretation of results from the static and mobile sensor networks.
